We will want to use the Pythagorean theorem
a^2 + b^2 = c^2
We can plug in the values we know
7^2 + 9^2 = c^2
49 + 81 = c^2
130 = c^2
We will then square both sides to get c by itself
c = 11.4 meters

Mrac [35]

Answer:

<h2> 14.7 %</h2>

Step-by-step explanation:

let us total the amount in her portfolio

Company A was worth $2690

Company B was worth $2980.

Total = $5670

when The stock in Company A decreases by 20%  she will have

$2690 *0.8=  $2152

Company A will worth $2152

when The stock in Company B decreases by 10%  she will have

$2980 *0.9=  $2682

Company A will worth  $2682

In all after the decline in are portfolio is $2152+$2682= $4834

the difference for the original amount in her investment is = $5670-$4834

= $836

The total percentage decrease in the investor's stock account

= (836/5670)*100= 0.147*100= 14.7 %

Trevor’s total employment compensation is $33,500. If Trevor has no job expenses and his gross pay is $28,600, then his total em
EleoNora [17]

we know that

Total\  employment\  compensation=gross\  pay+employee\  benefits-job\  expenses

in this problem

Total\  employment\  compensation=33,500\ dollars

gross\  pay=28,600\ dollars

job\  expenses=0

Step 1

Find the total employee benefits

Let

EC------> total employment compensation

EB--------> total employee benefits

GP------> gross pay

JE------> job expenses

EC=GP+EB-JE

33,500=28,600+EB-0\\ EB=33,500-28,600\\ EB=4,900\ dollars

Step 2

Find the percentage of the total employee benefits

we know that

total employee benefits is equal to 4,900\ dollars

gross pay is equal to 28,600\ dollars

by proportion

\frac{28,600}{4,900} =\frac{100}{x} \\ \\ x*28,600=100*4,900\\ \\ x=\frac{100*4,900}{28,600}

x=17.1%

therefore

the answer is the option

d. 17.1
